95. The United States Expedition to Japan, under Commodore M. C. Perry, 
1852-4, was not undertaken for scientific purposes ; and no special provision 
was made either for collecting or describing objects of natural history. A 
large number of shells, however, were obtained, and identified by Dr. Jay of 
New York. In Vol. II. of the ‘Narrative of the Expedition, &c.’ (Washing- 
ton, 1856, pp. 289-297) is given a list of Japanese shells, with descriptions and 
figures of the (supposed) new species. The following are related to the mol- 
luscs of the West Coast t. Specimens of the most important may be seen 
in the Cumingian Collection. 
* The M. mutabilis, described on the same page from Kagosima, is a Septifer; it is pre- 
sumed that the learned author did not open a specimen. 
+ The student should also consult, for related forms, the ‘ Mollusca Japonica’ by Dr. 
W. Dunker, Stuttgart, 1861 ;—like all the other works of the same author, most valuable 
for the patient care, accurate judgment, and enlarged experience displayed ; but relating 
chiefly to the subtropical portion of the fauna.
